由于管片衬砌结构的特殊结构形式，其在设计荷载作用下的结构响应会因相邻环之间的相互作用（耦合效应）而呈现出明显的三维性。本文通过三维数值模型研究了耦合效应的相关现象，确定了耦合效应的主要参数，并分析了耦合效应对真实的衬砌结构响应的影响。与目前在衬砌设计中采用的通常的平面模型的比较提供了重要的结论，耦合效应的影响和条件，其中变得更加相关。
The particular configuration of segmental tunnel linings produces that its structural response in front of usual design loads could present a significant three dimensionality due to the structural interaction between adjacent rings (coupling effects). The present paper studies the phenomena associated to coupling effects, determines the main involved parameters and analyzes their influence on a real lining structural response by means of a 3D numerical model. The comparison with the usual plane models currently employed in linings designs provide significant conclusions about the coupling effects implications and the conditions in which become more relevant.
